This invention relates to a screen structure especially designed and adapted for use with metal window frames although also capable of other uses.

"One of the principal objects of the present'invention is to provide a screen of this character which may be constructed entirely of metal and which, while of simple con struction and of light weight, is nevertheless strong and durable and su'liciently stiff and rigid to retain its form and to stand up in use.

Anotherobject of the invention is to provide a screen which isso constructed that its frame may be made up of small pieces of metal. and, if desired, may be constructed romthe scrap metal which results `from the manufacture of single piece metal window frames.

Another object of the invention resides in the provision of a screen which has a frame of such character as to permit of the easy assembly of the wire mesh or screening therewith and which also operates to maintain the wire mesh or screen properly drawn or tightened and tensioned thereby avoiding sagging or bulging of the screen and providing a well appearin screen.

Other objects and adventages reside in certain-novel features of the construction,

, arrangement and combination of parts which Cil will be hereinafter more fully describedand particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part ot this specification, and in which: l

Figure 2 is a view of the screen in rear elevation, the `screen being shown detached from the` window `frame Figure 3 is a view in transverse section on line f0L-3 of Figure 1; and

Figures 4 and 5 are detail sectional views taken on line 4 4 and 5 5, respectively, of Figure 2. y

"Referring to the drawings, and more particularly to` Figures 1 and 3, the numeral 1 designates a metal window-frame, having a sash frame 2. The construction of the metal window frame and its sash 2 per se form no part of this invention but for a full disclosure of the structure of these parts reference is made to my copending application for metal window structures, filed July 1, 1929, Serial No. 374,994. For the purpose of the present invention it is su'llicient to understand that the metal window frame 1 has an inwardly directed marginal flange 3 around its outer portion (see Figure 3) and this fla-nge 3 is utilized as a support for the screen as will be hereinafter more fully described.

The screen embodying the present invention includes a rectangular metal frame designated generally at 5 and a piece or section of wire mesh or screening designated generally at 6. The rame is made up of two similar frame members or sectionsdesignated generally at 7 and 8, respectively, A

assembled in face to face and partially inten itting relations, as will hereinafter more clearly appear. The outer section 7 includes U-shaped end portions 9 and 10 and side strips 11 and 12. The U-shaped end portion 9 has a long leg 13 at' one side and a short leg 14 at the other. The other Ushaped end portion 19 has a similar long leg designated at 15 and a similar short leg designated at 16, but the legs 15 and 16 are arranged on the opposite sides of the frame from the legs 13 and 14.

The complementary inner frame member 8 is similarly constructed in that it `has U- shaped end portions 1'? and 18 and side strips 19 and 19. The U-shaped end portion 17, which is directly behind the U-sliaped end portion 9 of the frontframe member 7 has a long legl 2O and a short leg' 21, the long leg 20 of the rear trame member 8 being behind the short leg 14 ofthe front frame member 7, as will` be understood from a comparison ofFigu'res 1 and 2.' Similarly, the short leg 21 of the `U`shaped end portion 17 of the rear Ylrame member 8 is directly behind the long leg13 oi the front frame member 'r'. This organization is also carried outin connection with the lower U-shaped port-ions of the frame members in that the U-shaped portion 18'ha`s`a long leg 22 directly behind the Cil short leg 16 o'l2 the front traine member '-.7 and this lui-shaped portion 18 also has a short leg 23 directly behind the long leg 15 of the front tra 'ie member 7. Eith this arrangement of the and short legs ot the iront and rear trame members, the side strip 11 overlaps trie end portion ot the long leg 22 ot the rear frame member. @n the same side of' the trame, the side strip 19 laps over the end portion of the long leg 13 of the front frame member. @n the other side of the trame the side strips 12 and 19 similarly overlap the long legs 2O and 15, respectively, on the op# posite ends of the trame.

As clearly shown in iiigure i, to adapt the nieces makin g up the frame 5 to have etlective ripping engagement with the screening or mesh 6 and also to stiften andstrengthen the ranie,ti,e iwf-shaped end portionsl 9, 10, 17 and 18 andthe side strips 11, 12 and 19 and 19 are provided. with longitudinal corruga= tions or crinps G and@ which are constructed to intertit inthe assembly and to grip between them the marginal portion ot the screen. Forholding' the `tl-shaped end portions and side strips ot' the frame assembled and in gripping engagement with the screen,

screws 25, 26 and 27 are provided, the screwsl 25 being engaged with registering screw threaded openings in the opposedend pertions 9, 10, 1'? and 18, the screws 26 having similar threaded engagement with the opposed side strips and the screws 27 connecting Cil the overlapping portions of the side strips andV long legs of the U-shaped end portions."

The screws, ot course, pass directly through the wire mesh and aid in thel fastening thereof. Y

For attaching the screen in position tothe window the frame 5 is provided with openings 3G adapted to receive attaching screws 31 whichare designated for threaded engager ment with internally threaded openings 32 provided-in the iiange 3.0i" the window trame. lhen the screen is applied to the window frame, the Jtrame 5 of the screen is held firmly again st the iianges 3 by the screws 31 as lshown in Figures 1 and 3.

With a screen of this construction the trame is stift, strong and durabie, is readily and veasily constructed, will firmly hold the screening or mesh properly tensioned, is readily attached to or talrenfrom the window Y frame, and permits of ready replacement of the screen mesh should this become necessary e or desirable.

ylfhe invention claimed is:

1. A screen having a frame including sepa rate front and rear trame members vassembled in face to face relation, each comprising a U- shaped end portion having egs of dii'ierent length and a pair of side strips, the side strips of one frame section overlapping the ends' 01"' the long legs or" the U- shaped end portions oi' the other frame, screening having its margin interposed between the frame sections and fastening devices for securing the frame sections together and clamping the screening therebetween.

2. A screen comprising a Jframe made up of separate front and rear trame members and having lengthwise corrugations, screening having its margin interposed between the 'frame members and releasable fastening device coacting with the frame members for se-V curing them together vand clamping the screening between and in direct engagement with the corrugations of both front and rear frame members. A

3. A screen comprising front and rear frame members assembled in i'ace to face relation, each of the frame members being made up ot a plurality ot sections of unequal length and being arranged with Yportions ot the-section ot the front trame member overlapping portions of other sections of the're'ar frame member, means ter securing the sections assembled and screening carried by the frame. e. A screen Acomprising front and Vrear trame members assembled in tace to 'tace relation, each` of the trame members being vmade lation each of the trame members bein made up of a plurality or" sections of unequal length and being arranged with portions oit' the section of the front frame member overlapping portions of other sections of the rear' trame member,screemng having its marginv interposedbetween said liront and rear frame members, said frame members having corrugations adapted to interiit in the assembly to strengthen and stiden the frame member and tension and Vclamp the screening, and means 'for securing the sections of the4 trame members together and for clamping the screening therebetween. 1

6. A screen having a frame including front and rear trame members assembled in tace to face relation, each comprising aU-shaped end portion having legs of diiierent length and a pair of side strips, the side strips ofone frame section overlapping the endsoi' the long legs ot the U-shaped end portions of the other frame, screening having its margin interposed betweenthe frame sections, said secber whereby to stffen and strengthen the frame and to tension and clamp the screening between the frame members and fastening devices for securing said frame sections t0- gether and for clamping the screening there- 5 between, said frame having means facilitating the attachment of thesereen to L Window.

In Witness whereof, I hereto alX my signature.
